SBIG ST-6 With CFW8 / CFW-6A Filter Wheel

This plug-in driver is available as part of the Obsolete Driver Pack.

For this driver, select SBIG ST-6 on the Setup tab.

The SBIG ST-6 can control an SBIG CFW8 or CFW-6A filter wheel. You must select the appropriate filter wheel Type. The CFW8 setting can also be used for Homeyer, Optec MaxFilter, and True Technology Custom Wheels with the optional SBIG compatibility mode.

SBIG CFW-6A filter wheels require a FILTER.CFG file. This file is produced by using the SBIG CCDOPS software to calibrate the filter wheel. The file must be copied from the CCDOPS program installation directory to the MaxIm DL program installation directory.

The user can assign names for each of the color filter slots, under Filter Name. If your filter wheel has fewer slots than allowed for by this driver, simply leave the Filter Name in the extra slots blank; they will not appear in the drop-list filter selectors. If the filters vary in thickness, a Focus Offset can be entered for each filter. This causes the focus position to be offset appropriately every time an exposure is taken with a new filter position. If this feature is used, absolute positioning focusers are strongly recommended to ensure repeatability.
